Really? Why?

ANSI.SYS was depreciated some decades ago; my understanding was that it was 
unsupported on Windows 7 and 8. Going back the dinosaur age makes little 
sense (and causes security issues).

There's really no good reason to use TUIs anyway; either write a proper GUI 
or use a browser for your interface (HTML is no harder to write than escape 
sequences). If that's overkill, then basic Put_Line is enough.
